Nutritional products retailer GNC has teamed up with US cable TV network Discovery Fit & Health to launch Transformation Diaries, an online TV series following four women working to achieve their personal ‘live well’ goals. In addition to their personalised webisodes, Transformation Diaries will chronicle each woman’s journey through first-person blog and video blog posts, providing online audiences with a monthly behind-the-scenes look at their struggles and accomplishments. The participant plans, which include exercise, nutrition and supplement regimens, will also be available online for viewers to follow.
